AIM

Jenkins + Packer.io + GitLab + Gogs, for automatically building the virtual machine images.

Jenkins Installation/Configuration

GitLab

Image Preparation

Using docker for installing gitlab. First pull the docker image back via:

$ docker pull sameersbn/gitlab:8.9.6

Also pull back the postgres and redis images, for we will link to these container’s services:

$ docker pull sameersbn/postgresql:9.4-22
$ docker pull sameersbn/redis:latest

Run GitLab

Create the data directory for holding the data:

$ mkdir -p /root/data/gitlab
$ cd /root/data/gitlab
$ mkdir redis postgresql gitlab
$ chmod 777 -R /root/data/gitlab/

Launch a postgresql container via:

# docker run --name gitlab-postgresql -d \
     --env 'DB_NAME=gitlabhq_production' \
     --env 'DB_USER=gitlab' --env 'DB_PASS=password' \
     --env 'DB_EXTENSION=pg_trgm' \
     --volume /root/data/gitlab/postgresql:/var/lib/postgresql \
     sameersbn/postgresql:9.4-22

Launch a redis container via:

# docker run --name gitlab-redis -d \
     --volume /root/data/gitlab/redis:/var/lib/redis \
     sameersbn/redis:latest

Launch the gitlab container:

# docker run --name gitlab -d \
     --link gitlab-postgresql:postgresql --link gitlab-redis:redisio \
     --publish 10022:22 --publish 10080:80 \
     --env 'GITLAB_PORT=10080' --env 'GITLAB_SSH_PORT=10022' \
     --env 'GITLAB_SECRETS_DB_KEY_BASE=long-and-random-alpha-numeric-string' \
     --volume /root/data/gitlab/gitlab:/home/git/data \ 
     sameersbn/gitlab:8.9.6

Systemd Services

For automatically startup the docker service in system boot, create the service items in systemd, listed in following:

Create the gitlab service:

$ vim /usr/lib/systemd/system/gitlab.service
[Unit]
Description=gitlab
Requires=docker.service
After=docker.service

[Service]
Restart=always
ExecStart=/usr/bin/docker start -a gitlab
ExecStop=/usr/bin/docker stop -t 2 gitlab

[Install]
WantedBy=multi-user.target

Also create another 2 service named gitlab-redis.service and gitlab-postgres.service, then enable the service via:

# systemctl enable gitlabpostgres.service
# systemctl enable gitlabredis.service
# systemctl enable gitlab.service

Then next time when system reboot, these service will automatically restart.
